This recipe keeps it simple but packs powerful flavor with just a handful of ingredients. Each one plays a crucial role: the buttermilk tenderizes and adds tang, sriracha delivers spicy kick, garlic amps up savoriness, and paprika brings warm color and depth.

Garlic cloves (4, minced): Fresh garlic infuses the marinade with robust, aromatic notes that awaken your taste buds.
Buttermilk (1 ½ cups): The secret to tender, moist chicken that practically melts in your mouth after grilling.
Mustard powder (1 tablespoon): Adds subtle warmth and complexity without overpowering the core flavors.
Sriracha (1 tablespoon): Brings just the right amount of heat to brighten and balance the richness.
Kosher salt (2 teaspoons): Essential for seasoning and drawing out flavor during marination.
Paprika (2 teaspoons): Gives the marinade a beautiful smoky hue and a hint of earthiness to round out the spice.
Chicken drumsticks (4, bone-in/skin-on): These ensure juicy bites with flavorful crispy skin when grilled.
Chicken thighs (4, bone-in/skin-on): Known for extra juiciness and rich taste, perfect for grilling.
Vegetable oil: Used to lightly oil the grill grates, preventing sticking and promoting those iconic grill marks.
Fresh parsley (¼ cup, chopped, optional): A bright, herbaceous finish to add a touch of freshness and color to your plate.

How to Make Grilled Chicken Drumsticks and Thighs Marinaded in Buttermilk and Sriracha Recipe

Step 1: Whisk the Marinade

Start by combining minced garlic, buttermilk, mustard powder, sriracha, kosher salt, and paprika in a medium bowl. Whisk these ingredients together until the mixture is smooth and well incorporated. This marinade is where the magic begins, as the tangy buttermilk tenderizes the meat while the spices infuse every bite with flavor.

Step 2: Marinate the Chicken

Place the chicken drumsticks and thighs into a large zip-top bag and pour the marinade over them. Seal the bag tightly and refrigerate for a minimum of 2 hours—overnight is even better for deeper flavor penetration. This step is crucial for juicy, flavorful chicken that pulls apart tender yet holds its structure on the grill.

Step 3: Prepare the Grill

When it’s time to cook, preheat your outdoor grill to medium heat. If possible, set up both a direct heat area for searing and an indirect heat zone for gentle cooking. Lightly oil the grill grates to prevent sticking and prepare for that delightful sizzle and those charred grill marks we all love.

Step 4: Grill the Chicken

Remove the chicken from the marinade, giving it a gentle shake to discard excess liquid—no need to rinse. Place the pieces directly over medium heat on the grill. Grill for about 16 to 18 minutes, turning occasionally so the chicken cooks evenly and develops a beautifully crisp skin. Watch out for flare-ups; if they happen, move pieces to the indirect heat side and continue grilling until they reach an internal temperature of 165 degrees Fahrenheit.

Step 5: Rest and Garnish

Transfer your perfectly grilled chicken to a serving platter and sprinkle with the chopped fresh parsley, if you’re using it. This adds a pop of color and fresh flavor to complement the smoky, spicy richness beautifully.

A white plate is filled with eight pieces of grilled chicken, including drumsticks and thighs, all with a crispy, dark brown char on the skin and sprinkled with small green herb bits. The chicken pieces have a mix of glossy, caramelized textures and slightly dry, charred spots. In the background, there is a blurred white dish holding grilled vegetables, including green asparagus, yellow zucchini slices, and deep red onions, all placed on a white marbled surface.

Garnishes

A sprinkle of chopped fresh parsley is my go-to because it adds brightness that cuts through the richness. You can also add lemon wedges for a zesty squeeze or a drizzle of extra sriracha if you’re in the mood for more heat. These simple touches elevate presentation and deepen the flavor profile.

Side Dishes

This grilled chicken pairs fabulously with sides like creamy coleslaw, grilled corn on the cob, or a crisp cucumber salad. For a heartier meal, consider roasted sweet potatoes or buttery garlic mashed potatoes. Each side brings a contrast—whether crisp, creamy, or sweet—that creates a balanced, satisfying plate.

Creative Ways to Present

For a casual feast, serve the chicken family-style on a wooden board with scattered herbs and lemon wedges. Or get playful by turning pieces into sliders stuffed with pickled veggies and slaw. Hosting a summer cookout? Skewer these drumsticks and thighs as part of a mixed grill platter with vegetables for a colorful crowd-pleaser.

Make Ahead and Storage

Storing Leftovers

If you happen to have leftovers (which often doesn’t happen because this chicken disappears fast), store them in an airtight container in the refrigerator for up to 3 days, keeping the flavors bright and the meat juicy.

Freezing

You can freeze cooked grilled chicken in a sealed freezer-safe container for up to 2 months. Just be sure to cool it completely before freezing to maintain the best texture and flavor.

Reheating

Reheat leftovers gently in the oven at 325 degrees Fahrenheit, covered with foil to retain moisture. You can also warm pieces in a skillet over low heat until heated through, adding a splash of broth or water if needed to keep things juicy.

FAQs

Can I use a different type of chili sauce instead of sriracha?

Absolutely! While sriracha provides a perfect balance of heat and sweetness, other chili sauces like sambal oelek or even hot sauce can work. Just adjust the quantity based on your preferred spice level.

How long should I marinate the chicken for best results?

At least 2 hours is necessary to impart good flavor and tenderize the meat, but marinating overnight is ideal if you really want those flavors to develop deeply.

Is it necessary to have both drumsticks and thighs?

Not at all. You can use just drumsticks or thighs, but including both offers a nice mix of textures and flavors since thighs are richer and drumsticks have great bite.

Can I bake this chicken instead of grilling?

Yes! Bake in a preheated oven at 400 degrees Fahrenheit for about 35-40 minutes, until the internal temperature hits 165 degrees. The grill adds smokiness and char, but the marinade’s tenderness shines either way.

What if I don’t have buttermilk?

No worries! You can make a quick buttermilk substitute by mixing 1 ½ cups of milk with 1 ½ tablespoons of lemon juice or vinegar, letting it sit for 5 minutes before using.
